In case you’re worried about “unprecedented” global warming, this might put your mind at ease.
Greenland Ice Sheet Project 2 (GISP2) ice cores show that temperatures in central Greenland have been trending downward for 8,000 years.
Anyone who tries to tell you otherwise is either lying or misinformed.
